Friedmann equations and cosmic bounce in a modified cosmological scenario
Ana Alonso-Serrano, Marek Liška, Antonio Vicente-Becerril
In this work we present a derivation of modified Raychaudhuri and Friedmann equations from a phenomenological model of quantum gravity based on the thermodynamics of spacetime. Sta…
New form of all black holes of type D with a cosmological constant
Jiri Podolsky, Adam Vratny
We present an improved metric form of the complete family of exact black hole spacetimes of algebraic type D, including any cosmological constant. This class was found by Debever i…
Symmetric Teleparallel Horndeski Gravity
Sebastian Bahamonde, Georg Trenkler, Leonardo G. Trombetta +1
Horndeski gravity is the most general scalar-tensor theory with one scalar field leading to second-order Euler-Lagrange field equations for the metric and scalar field, and it is b…
Emergence of quadratic gravity from entanglement equilibrium
Ana Alonso-Serrano, Marek Liška
In this work, we derive the linearised equations of quadratic gravity from entanglement equilibrium of local causal diamonds. Rather than starting from the Wald entropy prescriptio…
Black hole encircled by a thin disk: fully relativistic solution
Petr Kotlařík, David Kofroň
We give a full metric describing the gravitational field of a static and axisymmetric thin disk without radial pressure encircling a Schwarzschild black hole. The disk density prof…
Black holes in non-local gravity
Luca Buoninfante, Breno L. Giacchini, Tibério de Paula Netto
In this chapter we present a status report of black hole-like solutions in non-local theories of gravity in which the Lagrangians are at least quadratic in curvature and contain sp…
Carrollian Motion in Magnetized Black Hole Horizons
Finnian Gray, David Kubiznak, T. Rick Perche +1
We revisit the motion of massless particles with anyonic spin in the horizon of Kerr--Newman geometry. As recently shown, such particles can move within the horizon of the black ho…
The Newman-Penrose formalism in quadratic gravity
Robert Svarc, Alena Pravdova, David Miskovsky
The quadratic gravity constraints are reformulated in terms of the Newman-Penrose-like quantities. In such a frame language, the field equations represent a linear algebraic system…
The three "layers" of graphene monolayer and their analog generalized uncertainty principles
Alfredo Iorio, Boris Ivetić, Salvatore Mignemi +1
We show that graphene, in its simplest form and settings, is a practical table-top realization of the analog of exotic quantum gravity scenarios, which are speculated to lead to ce…
Comparing second-order gravitational self-force and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries II: the large-mass-ratio case
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We compare recently computed waveforms from second-order gravitational self-force (GSF) theory to those generated by a new, GSF-informed, effective one body (EOB) waveform model fo…
Comparing second-order gravitational self-force, numerical relativity and effective one body waveforms from inspiralling, quasi-circular and nonspinning black hole binaries
Angelica Albertini, Alessandro Nagar, Adam Pound +4
We present the first systematic comparison between gravitational waveforms emitted by inspiralling, quasi-circular and nonspinning black hole binaries computed with three different…
Covariant classification of conformal Killing vectors of locally conformally flat -manifolds with an application to Kerr-de Sitter
Marc Mars, Carlos Peón-Nieto
We obtain a coordinate independent algorithm to determine the class of conformal Killing vectors of a locally conformally flat -metric of signature modulo conformal…
Dragging of inertial frames by matter and waves
Jiří Bičák, Tomáš Ledvinka
In this paper, we review and analyze four specific general-relativistic problems in which gravitomagnetism plays an important role: the dragging of magnetic fields around rotating…
Accelerated Black Holes beyond Maxwell's Electrodynamics
Jose Barrientos, Adolfo Cisterna, David Kubiznak +1
Theories of non-linear electrodynamics naturally describe deviations from Maxwell's theory in the strong field regime. Among these, of special interest is the recently discovered M…
Unruh-DeWitt detectors in cosmological spacetimes
Aindriú Conroy
We analyse the response and thermal behaviour of an Unruh-DeWitt detector as it travels through cosmological spacetimes, with special reference to the question of how to define sur…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
ADM mass in warp drive spacetimes
Sebastian Schuster, Jessica Santiago, Matt Visser
What happens when a warp bubble has mass? This seemingly innocent question forces one to carefully formalize exactly what one means by a warp bubble, exactly what one means by havi…
Extreme mass ratio inspirals into black holes surrounded by matter
Lukáš Polcar, Georgios Lukes-Gerakopoulos, Vojtěch Witzany
Inspirals of stellar-mass compact objects into massive black holes, known as extreme mass ratio inspirals (EMRIs), are one of the key targets for upcoming space-based gravitational…
Penrose junction conditions with : Geometric insights into low-regularity metrics for impulsive gravitational waves
Jiri Podolsky, Roland Steinbauer
Impulsive gravitational waves in Minkowski space were introduced by Roger Penrose at the end of the 1960s, and have been widely studied over the decades. Here we focus on nonexpand…
Noether charge formalism for Weyl transverse gravity
Ana Alonso-Serrano, Luis J. Garay, Marek Liška
Weyl transverse gravity is a gravitational theory that is invariant under transverse diffeomorphisms and Weyl transformations. It is characterised by having the same classical solu…
Light propagation in a plasma on an axially symmetric and stationary spacetime: Separability of the Hamilton-Jacobi equation and shadow
Barbora Bezdekova, Volker Perlick, Jiri Bicak
The properties of light rays around compact objects surrounded by a plasma are affected by both strong gravitational fields described by a general-relativistic spacetime and by a d…
Numerical-relativity validation of effective-one-body waveforms in the intermediate-mass-ratio regime
Alessandro Nagar, James Healy, Carlos O. Lousto +2
One of the open problems in developing binary black hole (BBH) waveforms for gravitational wave astronomy is to model the intermediate mass ratio regime and connect it to the extre…
Adiabatic equatorial inspirals of a spinning body into a Kerr black hole
Viktor Skoupý, Georgios Lukes-Gerakopoulos
The detection of gravitational waves from Extreme mass Ratio Inspirals (EMRIs) by the future space-based gravitational-wave detectors demands the generation of accurate enough wave…
